GREASE CUP.

Application filed September 16,1921. Serial No. 501,160.

Y Beitknown that'l, JOHN OWENS, va citi i ingl is 'a specification. v

This invention relates to grease'cups and more' particularly to those grease cups that are attachedto the bearingparts of automobilesor other vehicles using greasein'f'a'semiifuid' condition. Y

S 011e of the objects ofthe present inventionr is tofurnish a grease cup that will rer mainqtightly closedafterthe grease is in` 'sertedj therein and y't'which can. be easily -opened for the insertion of additional-sup- -that when lgrease is'forced from a grease gunl or similar apparatus into Ithe cup, 1t

plies of grease, and furthermore' will exi 5" Ychide .diift or dust'jfnom the mouth of *the 2o A 'Y cup. Y y Another object of the lnvention is to so -a-ttach the parts of the cup and nozzle that the Vcannot readily be detached or become lost; c

` v arrange the lparts of .the cup and cover that Another object of theinvention is to so the cover mav be readily removed anda nozzle properly constructedv may be readily attached to the cup after thecover has been removed,V thev nozzle"Y` being sol constructed AAi will not be'allowed to escape around they fiti :tings of the parts.

, y W'ith the foregoing objects outlinedand .other objects in view whichwill appear as the descripton proceeds, the invention .com

si'sts in the novel features hereinafter de` scribed in detail,V illustrated in the accom panying drawing and more particularly Y pointed out in the a'ppended claims.

Referring to Ithedlfawing Figure 1 is a sect'onal view of the grease i cup-attached tothe' parts to be lubricated with the top attached to the cup;

Fig is a sectional view of the cup re- :moved and-the nozzleattached to thecup.

ln'the drawing l'tdesignates the cup which therefrom pins 2 to co-act with a suitabie bayonet slot in theftop 3 of the cup. lhe top or cover for the cup may be cylindrical "in yform to snuglyfit the outside-of the cup and hastherein a piston-like stopper 4 with aVv projection 5 extending therefrom having Evan enlarged head 6. The projection 5 eX- tends through a hole j? in the top of thel cover and aspring 8 `around theprojectionv 5 and between the piston-likejpart f1 and' the top oi thc cup holds the piston-like part inV contact with thetop of the cup.

The pi'stondike 'pai-o4 shouldof course have seating surfaces 9 to fit corresponding surfaces on the endo'f'the cup. lt is with# in the scope-loi this'invention to have these surfaces either conical'lin sha-pe, or flat, or otherwise just'so one surface lits upon the other to prevent the'egress of grease and the ingress of dust and dirt. Y

n The cup may have a ball valve 10v iitting in a corresponding opening in Aal nut 11 screwed or otherwise'fastened inthe top of the cup",v the nut 11 forming the valve seatv and being easily removed to take out the valve 10 or for repairs, cleansing, etc.

A'The valve 1() maybe held to its seat by a spring 12 which may be conveniently seated on a ledge 18 in the cup.

The valve 10 may have extending thereA from'a projection 14 comprising a neck part and a head suitably shaped for the attachment thereto of the end of the spring 12.

The construction shown has been found to vhe eihcient for holding the valve to its seat but evidently various other devices might substituted therefor.

. When it is desired that grease be inserted into the cup the top may be quickly removed by unfastening the Vbayonet slot joint and attaching to the cup the nozzle shown'in Fig. 2. This nozzle comprises a cylindrical part 15 of a size and having therein a bayonet slot similar to that of the cup cover 3. The cylindrical part may have a threaded top into which may be threaded a nut 16, the nozzle 17 having thereon a shoulder 18 againstwhich the end of the nut 16 rests.

The Vend of the nozzle 19 is made to closely fit the interior of the cylindrical part 15 and also the end of thecup 1.

It is evident from the construction shown that the cupv cover 3 may be easily 'removed from the cup and the nozzle having the cylindricalr part 15 attached instead of the cover, then by giving the nut 16 a turn or two lthe end of the nozzle may be brought and kheld into ,close contact with the end of the cup so that when pressure is put upon the grease in the grease gun to force the same through the nozzle into the cup, the grease cannot escape by oozing through the closely fitting parts.r

It may also he readily seen. that the cylindrical 'part ot the cover cannot become detached 'frein the @over and be lost, noi' can the parts oil the nozzle be easilv detached' and become lost. While at the saine time they are adapted to he quickly detached and attaehed when grease is fo he forced into the bearings. Even if the nut 1G should hee-orne entirely unscrevved from the Cylindrical portion 15 it cannot be lost since the parts would he still held together, rnor will the valve 10be Veasilyidisplaeed or lost.

AVVFrom the oregoingl I believe that the een# struction, .operation vand-advanltae'esloit rnv 'improved cup and nozzle will' berea'dily understood by those skilled 1n the art and I ain' aware that various Changes inl'v he made in the construction .illustrated Without departing from the spirit of the invention expressed in the'following claims.
